I bit mine for a long time, and then just stopped one day. I have no idea what I did, but all of a sudden I had nails that were worth painting and making pretty. So now I shape them and paint them once a week, if I remember, lol.
Mostly I just let them grow out for a bit, then clip and file them and no polish. Sometimes I'll get the urge to polish them or do my own fake nails. I don't spend much money on something that takes so much upkeep.
At the moment natural and breaking. I usually get them done, but have not in a bit. I tried the fake nails for one night when I went out last weekend and I took them off the next day. I have these sticky nail designs that I am going to try next.
I bite my nails. There are a few advantages to doing so, I guess. I don't have to worry about seriously hurting myself when I itch something; having more of the finger exposed allows me to do delicate work; and having nails that don't go beyond the nail bed makes it easier to play my guitar. However, my fingers don't really look good, and I'm sure that biting my nails isn't good for my tooth enamel!
Mine naturally grow rounded at the tip so I just let them grow and cut them if one breaks or they get stained from food or something. I paint my own and love fun colors as well as golds,pinks and nudes or I just leave them. The pink in my nail is very pink and the tips are clearish so no need for a french manicure. I hate fake nails especially having them removed. The only time I will get my nails done at a salon is when I get married or if I'm in someone else's wedding again. I'd rather spend the 30$ on something else.
I used to not be able to grow my nails out because I played the violin. When I stopped, I realized how much fun I had been missing out on. Until recently I spent a couple of hours a week doing something fun and creative (oh god I needed a creative outlet so badly). I've done some pretty cool things and I'm proud of myself.
